After a power failure, you noticed that one of your cluster database instances did not start automatically, whereas all other instances came up successfully. What would you do to determine the precise cause for the instance startup failure? (Choose three.)

• A.Reboot the node where the failing instance resides to check if the problem is persistent.
• B.Check for OCR corruptions by using the OCRCHECK command.
• C.Check if the Oracle Clusterware is functional by using the CRSCTL command.
• D.Check the alert.log file that belongs to the Oracle Clusterware software.
• E.Check the resource state by using the CRS_STAT command.
• F.Enable extra debugging in the Oracle Clusterware software by using the CRSCTL command.
• G.Check the alert.log file that belongs to the instance that did not start.

View the Exhibit and examine the diagram of the RAC environment implemented on a Linux platform in your company.
As a senior DBA, you have been assigned the task to implement ASM in this environment. You configured the raw devices that you plan to add to the ASM disk group.
How would you create an ASM instance on each node? (Choose all that apply.)

• A.by using the oracleasm configure command on both the nodes
• B.by using the oracleasm configure command on any of the nodes
• C.by using the ASMCMD command-line utility on both the nodes
• D.by using Oracle Universal Installer (OUI) on any one of the nodes
• E.by using DBCA on all nodes
• F.by using Database Configuration Assistant (DBCA) on any one of the nodes

View the Exhibit and examine an installation step of Oracle Enterprise Manager Grid Control 10gR2 to manage your RAC installation. You entered the host name but you are not sure about the port number. Thefollowing is the list of port numbers from the host ed-otraclin17b.us.oracle.com:

• A.3938
• B.4889
• C.1521
• D.5561
• E.1158

You decide to change the redo thread of one of your database instances.
Now you have only two threads: thread 1 is currently being used by instance RAC01, and thread 2 is currently being used by instance RAC02.
In which three orders could you perform the following commands to add thread 3 to your
database, and ensure that instance RAC01 is using thread 3? (Choose three acceptable orders.
1 srvctl stop instance -d RACDB -i RAC01
2 ALTER DATABASE ENABLE THREAD 3;
3 ALTER DATABASE ADD LOGFILE THREAD 3 GROUP 6;
4 srvctl start instance -d RACDB -i RAC01
5 ALTER SYSTEM SETthread=3 SCOPE=SPFILE SID='RAC01';
6 ALTER DATABASE ADD LOGFILE THREAD 3 GROUP 5;

• A.6,3,2, 5,1
• B.2,5,1, 4,3
• C.3,6,5, 2,1
• D.2,6,3, 5,1
• E.6,3,5, 2,1
• F.2,5,1, 4,6

View the Exhibit.
You are asked to help a colleague to logically remove node NLEDUC2 from a RAC cluster
installation.
On observing the colleague's terminal, you notice the output as seen in the exhibit. Based on this,
which five additional steps would you recommend? Do not be concerned with the correct
sequence for the steps.
(Choose five.)

• A.Stop and restart the clusterware on NLEDUC1.
• B.Check that the node has been removed from the database and ASM inventories.
• C.Check that the software has been removed from the database and ASM homes on NLEDUC2.
• D.Remove the node from the clusterware.
• E.Check that the ONS configuration has been updated on the remaining node.
• F.Check that the database and ASM instances are all terminated on NLEDUC2.
• G.Stop and restart the nodeapps on NLEDUC1.
• H.Remove the listener from NLEDUC2.
